Just finished up our 8th trip, to Mt Hood. Here are two more photos that show some detail.
The sliding door window screen is made from ordinary flexible fiberglass screen mesh. A 36" x 84" roll ($10 at HD) is enough for both side windows. The edges are bound with duct tape, and 1/2" rare earth magnet disks are embedded about every 6" in the folded tape. NOTE: the door panel itself (aluminum?) isn't attracted by the magnets, but the chrome strips above and below the window are strongly attracted. Size carefully so the magnets lay on those strips.
To hang those battery-operated fans, I cut a 38" long strip of 1/4" thick, 1/2" wide wood. With the rear sunroof shade retracted, that strip neatly bridges between the shade tracks, avoiding any tension on the headliner. You can also see that we fitted custom pouches for personal items onto plastic coat hangers; these just hang from the van's coat hooks.
To keep clothing organized, we use individual backpacks. By adjusting the backpack straps, we found they can hang on the headrests of the front seats. This keeps clutter off the floor, which keeps Penny happy, and when she's happy, we're happy!
I've also rigged up a better electrical setup for the Jackery 300Wh power pack. When the van's running it charges up, and when the van's off, the input automatically switches to a jack under the front seat where I can plug in a cable from a solar panel. No pix of this but if there's interest I can provide details and a schematic.
If you want more gory details of how the camper was designed and built, there's a detailed video
